Comments
and opinions from prior months
July 2011
1) Qu.
How can schools at Dorney ever win the Victor Ludorum
when clubs have such
a large entry. ?
Ans. The
perennial question ! There is a limit on the total
seats any club can
enter, traditionally 40, but admittedly few schools can match that for
numbers. Another limit is that Nat Schools or Champs entries
should not
enter The Ball.
Clubs
will respond that they cannot match a previously suggested criterion
that all
their club crew entries should come from the same school, with
VL scores
declared based on those schools.
Here’s
a suggestion……Would
competing schools like us to present an extra VL trophy for
schools only
? The current main VL scorings would stay the same; if a
school
wins both, which seems currently unlikely, so much the case. Let
me have
your opinion, and discuss further with Phil Clements on his Dorney web
site.
2)
Qu. We have
seen Ball
entries at the Nat Schools and Champs. Is this not cheating?
Ans. Personal integrity issue
here. Schools that do
enter Nat Champs or
Schools often enter The Ball, but we trust them to only enter
competitors that
are not good enough to enter the big regattas. We have asked two
clubs in
the past to desist from entering The Ball on this issue, and a further
3 or so
have, at their first time of entering, put in crews outstandingly
better than
the average. They have apologised and tempered entries to follow.
If you
suspect, politely enquire, and inform Phil Clements
3)
Qu. The
coxed sweep fours entries for schools that traditionally constituted
the
original competition are nowadays seemingly rather thin on the ground,
particularly the second fours. Is it time to change the entry format ?
Ans. Seems strange, but this is not
really a rowing
question. The original Ball Cup was for 1st and 2nd
sweep coxed fours, and has been offered as such for over 70
years. These
events are part of the national rowing chronicle, and indeed The Ball
Cup, with
its sweep events, was a highlight at a Henley Royal Regatta exhibition
in
recent times. The two events exist to remind us of the origins of
the
regatta that so many now enjoy in a plethora of optional forms.
They are
on the programme for this main reason. There are, of course limited
numbers of
schools that sweep row only, but they do exist in approximately the
same
numbers as the pre- 1960s Ball Schools. Schools contacted so far
on this
subject do not want the events changed, so, you schools, let’s
have a pair of
entries from you in 2012 !
4)
Qu.
The Ball Cup Regattas are super events ! Who are the
personalities that
we should thank for these highly organised friendly regattas ?
Ans. Cometh the hour ! The
history of The Ball is on
the home page, not
all recorded, but it is certainly the case that if Katina Bonham of
Evesham,
Michael Righton, then of Dragon School and Keith Osborne in the north
had not
taken up the baton at the turn of the century, The Ball would have
floundered. Graham Middleton, lately retired, carried on from
Michael, and the huge Southern event is now brilliantly
master-minded
by Phil Clements, assisted by Barbara Wilson, Keith Broadhurst, a team
of
volunteers, umpires, the ARA launches, and more, too many,
apologetically, to
mention. The Henley Stewards Charitable Trust, under Mike
Sweeney,
himself an original ‘Ball Boy’ at Becket School, provide
each year the finance
to cover the huge background expenses regarding venues, trophies and
much more.
The
Northern Ball started as a one-off in 2000, prodded by the
indefatigable Keith
Osborne. Warrington Rowing club, under Richard Sinnott, hosted
the event
several times, Hollinworth Lake once, and Runcorn RC with The Grange
School
twice. Calendar dates are becoming difficult to find, with the pressure
of
exams, and in 2011, Runcorn RC, with Simon Leach and Val Edwards, is
working in
conjunction with The Ball Cup to host a full blown Junior event.
The search still goes on for a permanent multi-lane course in the north.
5) Qu. We enjoyed
your coaching
courses at Tideway. Do you run them elsewhere?
Ans.
The Ball coordinator is a BR Coach Educator, and is visiting
clubs to
introduce parents to the club coaching team. We find it productive to
teach as
many people as possible to coach properly, rather than solely coach
rowing
members, the facility for which is still available at the TSS, Imperial
or Eton
courses. The Ball parent courses are weekend, and assume that the club
has all
the safety requirements in place, including the basic BR courses.
Concentrated coaching technique guarantees any parent the ability to
safely
control and coach a crew of novices.

Qu. How
can I rig my own sculling boat ?
Ans. Easily
! Don’t be put off by those that think rigging is a complex
science.
Rigging is the adjustment of
equipment to
enable a sculler to perform comfortably and efficiently. It
is true
that at a high level, fine tuning adjustments can be made, but the
following
will hold true for the average sculler. It is important to
follow a
sequence – do not listen to anybody that starts to adjust items
randomly.
a) Adjust sculls to match
the boat. Set sculls at 88 cm from button face to end
of handle,
ignoring the curved ends ( you cannot pull with these ! ). Adjust
rigger
span ( from outside of one top nut to the inside of the opposite )
to 159
cm. Make sure that any pin adjustment in or out is equal on each
side. It
is comfortable convention to have the LH gate about 0.5 cm higher than
the
right. Measure this vertically from a straight edge placed across the
sax-boards. Do this now, and do not measure the actual height
– it is not
relevant. Neither count washers – the riggers might
be slightly deformed.
Simply make the left a little higher than the right. The actual
height
comes later.
b) Sit in the boat with sculls
and loosen the stretcher. Put feet in stretcher and move to the end of
the
stroke, hands drawing comfortably to the finish, taking the stretcher
with you.
Fix the stretcher when the handles are about 5 inches or 12 cm apart.
c) Loosen the rails on the
slide bed ( thumbscrews are under the deck; access through the hatch
cover.) Come up to a comfortable beginning position. Adjust rails
until
you are just touching frontstops. You do not want rails sticking
out into
the footwell, neither do you want to be hammering frontstops. Your
shins will
be approximately vertical.
d) Scull
height. Sit in the boat at backstops, legs down, back vertical
and flat,
stomach in.
Turn scull spoons vertical, and lower handles to
just touch
thighs. Hands on top of sculls. The sculls should be about a tennis
ball
distance off the water. ( it helps for another person to hold the stern
of the
boat for balance ). Adjust gates up or down equally to obtain
this
clearance. Again do not count washers, just adjust an equal amount up
or
down. Do not listen to anybody that quotes a measurement for this
height
– no boat is going to fit every body to a consistent set of
figures.
e) Nearly
there. Stretcher now. Your stretcher will have
moved
fore and aft to obtain the finish. It will also move vertically
to make
your feet higher or lower. If your calves interfere with the slide bed
or rails
at the end of the stroke, adjust the stretcher bed higher until this
ceases. The angle of the stretcher ( rake ) will also
adjust. Most
will be set average OK, but if your toes are pointing towards the stern
when
you drive, steepen it. If your heels are rising uncomfortably so
that you
tend to slip down into your shoes, adjust to a lesser
slope.
The last two adjustments will involve nearly taking the stretcher
to
pieces – be careful that you can put it back together. Some
stretchers
can also adjust the angle between feet – more splay for the less
flexible – but
not all. If the latter 3 actions worry you – ignore them.
f) Lastly, you will need a
pitch gauge ( and somebody to show you how to use it )
Set your gates so that they are over-pitched ( lean
forward
) by about 5-6 degrees. Less, and the sculls will dive deep, more they
will
wash out as you draw.
The above may sound lengthy, but it is amazing how
many
scullers try to compete with equipment a million miles away from the
recommended. Spend a session on this. ! You may
have to
lift the boat in and out of the water a dozen times – use a
helper and have
patience ! The time spent will win you races !
2)
Qu. Macon
or Chopper Sculls for juniors ?
Ans. Any
comment on this subject will be controvertial,
but believing that opinion should be backed up by reason, here goes !
How many cyclists or motorists a hundred years ago
persevered with solid tyres when pneumatics were invented ?
No prizes
! Similarly, the chopper blade made the Macon
blade
obsolescent, just as the Macon did to ‘pencils’. Why
? One of the
biggest ‘stoppers’ in sculling is the backwatering effect
by the loom just
above the spoon. As the scull moves through the water, it also rotates
about a
point near, but not at, the spoon base. So part of the shaft moves in a
direction opposite to water movement, and is the equivalent to dragging
a hand
over the side of the boat, or worse. The Chopper loom is not
central to
the spoon, and thus moves to a large extent above the
surface,
negating the backwatering. In addition, and relevant to the next
paragraph, its purchase on the water is more ‘solid’
– an increase
in mechanical efficiency, but a worry for young backs.
We thus notice
that
many clubs, having a surfeit of Macons from ages past, or, in my
opinion,
wrongly purchasing them anew, use them for juniors because they have a
‘softer’
beginning and are thus easier on backs. All true so far !
BUT,
looking ahead, are we not in this game for racing, and as efficiency
increases,
the Macons need a quick beginning to cancel out their mechanical
drawbacks. Our
improving juniors thus adjust to get the best out of the outdated
equipment. We arrive at the point where they are judged to have
improved
to such a degree that they are introduced to choppers. Instinct
rules;
beginnings are fast, and ‘OUCH’, back
injuries. So what do we do ?
Simple ! Throw away all the Macons – or
imagine that
they had never existed. Start on
Choppers. ( Do I
hear howls of derision?! – Read on )
We must teach our juniors that considerable
resistance will
be felt in the lumbar region, and linked to the fact that most novices
do not
have ideal back posture, it is incumbent upon coaches to move carefully
in this
area.
How ? I do the following, and have never
had a
junior with a back problem.
Don’t go near the water with your beginners
!
Place two old car tyres on the ground and place a sculling boat with
choppers
on them. Wedge if necessary to allow a sculler to sit in the
boat. The
sculler hold s the sculls as if on water.
Coach ties a long cord or rope around the base of
the spoons
to make a long loop and stands with the loop beyond the bow, behind the
sculler. The sculler is instructed to ready themselves for
a
‘stroke’ about threequarters forward, and the coach takes
up the
slack. The sculler is instructed to gradually try to draw
the
blades by leg drive, holding back firm, against the increasing
resistance of
the coach, who tries to prevent movement by increasing rope
tension.. At stalemate, the sculler will adopt a
‘perfect’ back,
and is held in that position for some 30 seconds. Relax.
{ It is amazing that the natural
instinct
of the body to adapt to its most efficient position completely negates
rounded
backs. Rounded backs only occur on the water because, being a
fluid
medium and not providing adequate resistance, water does not call upon
the body
to adapt its maximum resistance position, an efficient back. Only
as
efficiency increases, does the sculler equate the now cerebrally
learned
land exercise to the water sculling action }
Back to the land drill. When the coach is satisfied that the back is
firm,
he/she ‘allows’ the sculler to slowly complete a whole
stroke against the rope
tension. This can be done in complete slow motion, the coach advising
all the
time. The backs will be firm but undamaged, as the nervous system is
ready for
the stress.. Several sessions later, or
whenever………… move to the
boat.
Choppers thereafter !

1) Qu.
My coach uses scientific terms when giving advice. I never
understood
them at school ! What chance now ?!
Ans.
My
sympathy to you both ! From the coach’s angle,
there is no
point in trying to do his/her job efficiently without simple but proper
terminology. From the pupils’ point of view, I will cover
some of the
more popularly used phraseology. Don’t think that you are the
only one with
this problem; even coaches at the highest level misuse physics
terminology. I will give an embarrassing example of this later.
Force. This is a quantity that tries to
make something move,
go faster or slower,
or if it cannot do this, to deform, or change something’s shape.
‘Force’ is a
family noun, with other sub-members of its family title to follow.
Commonly,
these are Weight, the attraction of the earth upon an object, Friction,
in common terms the ‘stickiness’ that
exists between two surfaces, or in
boat movement between a hull and water. It tries to slow down
movement. Tension This is the force that
exists in, for example a rope,
when trying to move
or change the movement of an object. A ‘pull’ force. Thrust.
This the opposite to tension; it is a
‘pushing’ force. A blade thrusts upon
the water in propulsion, it thrusts upon the rigger pin ( By the
way,
whenever something thrusts upon something else, the receiving item
thrusts
back– this thrust is called a Reaction) .
OK ? Have
a cup of tea, and list and learn the above!
Movement. How fast a body is moving is
called its Velocity, which
is a posh word for Speed. ( OK, you academics, I do
know
the difference
between distance and displacement, but am trying to help those in need
-
simply !) It is how far (in metres) A boat moves in a
second.
This is measured simply in metres per sec, or m / s , (or for
mathematicians in
‘power’ terms that I cannot make my computer print !)
If a boat goes Faster,
it has an Acceleration for a period. Technically, and
don’t worry
over this one, it is a measure of the increase in speed every
second.
Units look confusing – forget them!
‘m/s/s’ or ‘metres per sec per
sec’ or m/s ‘squared’ ( Again, gooks, don’t
write in !) Simply
remember Speed ( Velocity ) = ‘How fast’
Acceleration = ‘Getting faster’ ( or slower )
Here is the
embarrassing one! A national coach was reported in
‘Regatta’ as saying
that current slide thinking was to accelerate forward with constant
velocity
!!!
Mars Bar
prizes for finding the article!
So now
you are already qualifying for your gold coaching awards !
Mass and
Weight I could give a lesson on
Newton’s Laws of
Motion here, but will resist, and break all the rules !
Most
coaches will refer to your ‘Weight’; some may use the term
‘Mass’. No
problem with either, take them as meaning the same –we know what
they
mean. ( to save email response time – yes, we do know that
mass is
measured in Kg, Weight in Newtons, and that numerically weight is 9.81
times
greater than Mass, but forget it ! )
Interestingly, some
coaches may mention Inertia. This is a term that
dimensionally (
measurement units ) equates with Mass. Descriptively, most lumps
of
matter ( you or me ) don’t want to move unless acted upon by a
force ( for
example, your mothers getting you up to go to school ) We thus
have a
high Inertia, an ‘unwillingness’ to move.
Distance, Length
etc.. No sympathy here, we must all know
that the
length of an Olympic rowing course is 2000 metres. Your rigger
span is
159 centimetres.
10 mm = 1 cm 100cm = one
metre 1000m = 1 km ( By the way, do not
mix up
‘metres’ ( distance ) with the device that is under the
stairs measuring gas
volume or electricity units (‘meter’ ))
Let’s talk about Work = Energy =
Force times
Distance applied ( Joules ), Power = Rate of doing work
(Watts )
another time ( if you are interested to continue, let me know)
Enough for now. That will surely
see you
through your season’s junior wins. Pull your coach’s
leg by asking
him/her some of the above. In answer to the original
email, Yes, you do need to understand simple physics!
2) Qu. I have
won several junior singles events and things
are getting technical. I have problems understanding
‘beginnings’.
I have heard that my body movement at the catch must
actually begin
before the blade engages the water ??
Ans.
Yes,
we could have big discussions here, BUT, I would like to relate back to
the
understanding of physics terminology, so………
You know already that in simple summary, at
the catch
the blade has to reverse its movement towards the bow, drop into the
water (
complex issues here – don’t worry ) catch up the water
passing the boat (
relative motion) and by attempting to move faster than this water
movement
exert a thrust upon the water, whose reaction forces exert a force back
upon
the blade and thereon the rigger pin, which propel the boat forwards.
The effective propulsion of the stroke is
dependent upon
the efficiency of this ‘catch’ and the propulsive force
which can be maintained
over an arc of blade movement. I’m teaching you to
suck eggs here –
you know all this ! But there is an interesting comparison
between
singles and quads here. A relatively slow single demands a longer
‘hang
on’ towards the end of the arc than the quad, whose movement is
so fast that an
experienced quad athlete will tell you that once the 90 degree point of
maximum
efficiency is passed, the main task is to forget further propulsion,
simply to
extract the blade efficiently with no drag, let the boat run and
prepare for
the next very efficient quick beginning.
Now read this ! Your
comment
about body movement ( I’ll call it ‘kick’ ) is terribly
valid.
And it’s all about more physics. !
If you think
that the ability to propel the boat is down to muscular effort only,
forget it!
Your body
needs help ! My TSS course students will remember me drawing
silly
pictures of a medieval storming of a castle. The dopey invaders
call up
the muscular heavyweights, who try to push down the gate – and
fail
miserably. The clever ones are the lightweight athletes (
yes, they
spelled it like that in 1357 ), who pick up a tree trunk, run it at the
door
and batter it down !
You can be dopey or clever.
However
strong you are, that strength alone will not propel a boat
efficiently.
But you have a ‘tree-trunk’ – your body ! Its
mass, if it can be moved,
provides a Momentum ( Momentum { more physics –sigh !} =
Mass times
Velocity ) So, a sculler with a mass of some 70-80 kg, starting
to move
his/her body as quickly as possible off front stops during that
fraction of
time that the scull ‘drops’, by the action of LEG DRIVE,
not body lift, or
worse, arm catch, adds a momentum effect ( Called Impulse ) to
the
muscular propulsive forces so wonderfully developed during those winter
gym
days. A better training compromise – work on leg
‘kick’at blade entry as well
as gym or ergo work. ( I remember telling young
scullers
at TSS to cover their ears as a certain international lightweight
sculler had
his language wonderfully amplified by cavernous Chiswick Bridge as he
practised
dozens of leg kicks – presumably not in that session achieving
too much success
at this very difficult task )
So, yes, you have heard correctly, but
do it by
LEG kick; use your body’s momentum and DRIVE
( Ask your coach why an ‘ergo’
(ergometer) is so named
. The answer is that in between old fashioned Imperial units such as
the Horse
Power and the Poundal, a brief foray into international units was made,
whereby
the ‘erg’ was the amount of energy expended by applying a
‘dyne’ of force
through a distance of a centimetre. Unfortunately, the units were so
small that
we were dealing in millions. They were scrapped and we use the
substitutes, the Newton, the Metre and the Joule. ( Ask me
about
these if you are interested ))
3) Qu.
‘Mankind
has never reached perfection in any
performance or design. Improvement is always
possible’ Will this be
true in rowing ?
Ans.
Given
that the Olympic boat, rigger and blade definitions instruct us to
perform our
sport within medieval equipment parameters, we can certainly examine
the
current search for that element which will give GB that vital sea
change that
will out- perform the world.
There are several approaches to research
development. We can, for example, take the current model and try
to
improve its efficiency. Problem here is that the current model is
possibly
rubbish !
So, as an alternative, throw away the
current
tools and start from scratch, bringing in technicians and theorists
that are
shown the task but not the previously used equipment.
Difficulty
with the this method is that it is on a par with Soccer management;
directors
are impatient – new design takes time and we want the quick fix
! The
‘Old School’ would also have a say !
Why not go down the cheat road
?
Just like the Japanese in the1950s and 60s, scour the world for the
very best –
and copy it ! Bit of a stand-still future here !
Of course, in rowing, we are
dealing
not only with human physiological development, which tends to advance
at a
pretty constant rate throughout the honest athletic world, but also
with
equipment of such complex and permissibly variable design, that in the
latter
may lie the holy grail – or is it in the joint application of
body, blade and
boat – a single machine.
Look at history – we
had of course
the sliding seat; more recently we had the Pencil – Macon
– ‘Chopper’
blade design evolution –that was meaningful !. In the
late 1970s along
had come a German school teacher named Karl Adam, who revolutionised
training
methods, transformed ‘fartlek’(Scandinavian distance
training) into
interval training and for a while made West German eights
invincible. At
a modest home level, in the 1970s this writer picked up an article on
the
distance track athletes glycogen shunt dietary approach, applied it to
a crew
of 16 year old schoolboys ( try doing it now !) and smashed the 31 mile
Boston
marathon record, beating the current GB four. Now every body does
it !
Here are my thoughts, which maybe
are a
gel mix of several of the above approaches. Firstly,
I tend
to respect, but not necessarily accept, historical commentary. As
example, I think in a book titled ‘Rowing, a Scientific
Approach’, I read that
crews that rush up slides are not at a disadvantage to those that adopt
a more
measured approach, the argument being that both crews are sealed units
contained within a boat, and that their internal movements, given
identically
efficient bladework, do not offer variability in their independence
from the
outside medium, the water. OK, so why does my observed very fit
novice
crew at a provincial regatta trail by several hundred metres behind an
equivalent elite crew. Somebody wrong in the theory ?
Not
obviously, so maybe there is another source of such variation.?
Another quote from
somewhere……, with reference
to energy expenditure in the mechanical functions of the moving racing
boat. ‘ Pitch - that up and down movement of
the boat, does
not have a deleterious effect on motion.’ What
?!!
Sorry, not acceptable. So off I go to find a boat full of athletes, and
lift
and allow the bow to fall – 150 + times!! Yes,
I am k…..d
! Ok, so I apply a bit of simple physics and work out the
average
energy of pitch as a percentage of crew energy expended
( not to difficult as an estimate), and find that pitch does have an
appreciable effect.
Moving sideways for just a moment, interesting how
different
investigators sometimes arrive, independently, at similar
conclusions.
Take contemporary observation of pitch by means of the water-expelling
tube
fixed to the moving boat.
( See ‘Rowing’ )
Now the big one for the future ! Resonance.
Sorry, I’ll say that again –
Resonance! More physics
! Yes, and here we go…. ‘Resonance is
the interaction of two
or more oscillations to give a net increase in amplitude of
one.’
QED – all solved ! ( Not really, I’m
joking )
So you would like it explained. An
oscillation is a repetitively performed phenomenon. A
child’s swing, the
pendulum on a clock, the pitch of a racing boat, the movement of a crew
up and
down its slides. In its purist form the oscillation is called Simple
Harmonic –
the projection onto an axis of a point moving in a circle at constant
angular
velocity ( Sorry –forget that bit !).
When two oscillations take place within
a unit,
they can combine in two ways; they either cancel each other to a degree
–
called destructive interference , or mutually support each other to
give an
increase in amplitude ( Physically, in rowing this is the amount of
movement )
– this is called constructive interference, or Resonance.
( Radio frequency tuning to give maximum volume is also a
constructive
combination of two radio frequencies) So the novice
crew’s
oscillations combine to give a resonance phenomenon – the pitch
increases to a
degree that its energy subtracts from that available to propel the
boat.. The international crews must
therefore
strive to achieve near zero resonance of the oscillatory movements
within the
boat. Their available energies are therefore channelled into propulsion.
The language might be scientific,
but the
artisan has a back door into physics - intelligent observation
and
‘feel’. Gully Nickalls, 7 times winner of The Grand
Challenge Cup at
Henley ( are you attending, Alan ), knew how to cancel resonance
– by feel
! The intelligent coach is using his water
spout
observations – by experimentation. Physicists are deriving
complex equations
for pitch motion, involving Archimedian forces, non pure SHM, as
is slide
movement, and combining the two to cancel resonance. Bit brain
blowing,
and 2012 gets closer !
The results, however obtained,
combine to
give as efficient a performance as is possible using currently
conventional
equipment. We can actually, by combining feel, observation of
experiment and
theory, actually already give an approximate contemporaneous ( now!)
working
model for eradication of resonance effects.
Moving on, what about these blades
with an
angle piece moulded on to the upper edge of the spoon ?
Gimmick or
revolutionary design ? My sculler has tried them –
definitely a more
efficient catch and drive, but if you scull your blade deep (see
‘backwatering’
last month ), the trial is futile.
We shall see ! The world awaits !
I’m going to see what HG Wells has to say !
4) Qu. Where do
you obtain the beautiful Ball Cup Medals
awarded at Dorney and Runcorn. Are they real gold and silver ?
Ans.
No
advertising restrictions on this site ! They are certainly real
gold and
silver – plated ! But where can you find as fine as
these.? Crescent Silver, Spencer St., Hockley,
Birmingham, B18 6DE. They will make and charge you for a master
mould to
your design, which is your property, then the medals at a very fair
rate. Ask
for Neil !

Qu.
Most
modern sculling
boats have ‘gull-wing’ riggers. What are the
advantages, if any, of these
?
Ans. Mixed
feelings ! The indisputable advantage
of gull-wing over conventional single riggers is lack of stress on the
boat. Conventional single riggers apply a ‘squeezing’
effect on the
shoulders, often constructed of wood within the laminated and gel-coat
skin of
a plastic boat. The inner wooden shoulders crack, lose their rigidity,
and the
outer skin, although flexing to a degree, eventually splits as
well. Try
flexing the riggers on an old boat and see the movement, especially if
thinking
of purchase.
Gull-wings, although capable of carrying considerable stress fore and
aft, or
compression across the boat in use, due to the aerofoil shape, can be
prone to
puncture or cracking strain in transit or storage, during
unconventional
movement loads.
Weight advantage is an irrelevance anyway if comparing with aluminium
conventionals. The difference is small, most of the weight of both
being in the
pins. Wet rowing clothing kit, for example, or an extra sweater, is far
greater
than the weight difference between the rigger designs !
Streamlining efficiency is indisputably greater in a gull-wing, but as
above,
the advantage is negligible. Learn to scull – there lies a real
advantage !
A
common problem with gull-wings is their professed advantage in the
ability to
adjust their fore and aft position in the boat. There will be
several cm
of option in this range, and although the design offer is beneficial to
the
expert rigger, the average sculler may have problem deciding on setting
the
gull-wing position.
Apart from sheer guess work, I take the trouble over a couple of
sessions to
adjust as follows. Acknowledged angles for a single between
sculls and
the centre axis of the boat are approximately 37 deg, measuring behind
the
sculler at the catch, and 137 deg at the finish. These are the
angles
where work starts and finishes ( Ouch, those hamstrings ! ) not
simply
the reach.
I find a
bridge underneath which the sculler can work at racing pace, and either
video
or take several exposures of the sculler from above. You will
eventually find a
good pic at either end of the stroke. Enlarge and print. Rule the
prescribed
angles and those achieved. The average club sculler will not
achieve the
prescribed angles, usually being up to 10 deg more at the beginning,
and
depending on too much lie-back, often too great at the finish.
Clue to
gull-wing setting is to photo in a conventionally rigged boat as
well. If
the recommended catch angle is easily achieved in the gull-wing, but
not in the
conventional, the wing is set too far towards the bow. Adjust until
comparable
with the conventional. ( More simply, measure the work line
across the
boat for a comfortable conventionally rigged single, and set comparably
for the
gull-wing. A rule of thumb for starters is that the line of work across
the
boat should be approx 5 cm towards the bow from the front stop position
).
Whichever, the vertical pic session throws up other clues, such as
stretcher
rake angles needing change as the knees are forced outside the arms,
the
beginnings taken on the sides of the feet, with the heels lifting
over-high.
Also obvious from plan view is the degree of rounded back in attempting
to
reach the beginning.
(
Knees should never reach outside the
arms at the beginning or any point, but end somewhere within the
arm-pit/chest
angle.)
( If any reader would
like some copies of these vertical pics, let me know )
The spacers between the
gull-wing and the boat hull can be used, if variable thickness, in
conjunction
with the gate washers, to set the height (see previous article) of the
sills.
Interesting is that there
is available a gull-wing which is set behind the sculler. I would
find
this a definite advantage in adjusting my stretcher
( an awful problem in most gull-wing boats ! ), BUT, what worries me,
and might
well cause any coach who understands the physics of moments
( leverage, not time !) to think, is a head-on study of the craft,
locating
handles, rigger pins and scull positions in the water. The handles are
higher
than the pins, both higher than the water position. There is a turning
moment
which tends to lift the boat slightly at the catch, the force being
applied at
the rigger mount area, the fulcrum – no apparently great
disadvantage.
If the rigger is
mounted behind the sculler, the point of application of the turning
moment, the
‘lift’, is considerably towards the bow. Is this an
attempt to minimise
pitching ? Is there another application somewhere in the design ?
Have a
good think !
We are probably
losing the drift of the question, so good luck with those gull-wings
– don’t
stack other items on or under them in the trailer!
2)
Qu. I
tend to row my
sculls deep during the stroke. I understand the drag problems, but how
do I
cure it ?
Ans. I
have often said during lectures that a sculling boat on its own is
potentially
a fairly fast-moving unit. The problems start when we put a
sculler in it
!
The
lesson starts with the above premise; a well rigged boat and sculls,
the
product of both evolution and design, knows what it is doing !
You, the
sculler, must not interfere, but accommodate to the equipment’s
requirements.
Let us
start by assuming that you have correctly and comfortably rigged your
boat and
sculls ( See previous forum ).
Sit at
back-stops, straight comfortable back, on the bones of the pelvis, not
spread
out like a jelly fish all over the seat. Lean slightly forward,
spoons
upright, arms straight, and place the blades in the water.
Observe.
The sculls
are floating on their own. Take your hands off
( careful ! ). The spoons will float with about 1 cm. above the
water.
This is the depth at which they must be drawn during the stroke.
Place only a forefinger over the handle of each scull, let them float
at their
natural depth, and slowly draw the handles towards you. You will
notice……….
1) The
handle does not come straight towards
you, but moves in an arc. This arc must be followed during the draw (
How ?
Later )
2) At some
point the ends of the handles
interfere with each other. This is why, during the rigging, the
starboard
gate can be adjusted about 0.5 cm higher than the port. Also, it is
convention
that the port scull slightly leads the starboard during the draw.
3) As the
handles approach the body, the L/R
symmetry can be re-established. The stroke ends when the handles are
about
10-12 cm apart.
4) The
elbows will tend to leave the body. How
much ? So that the forearm makes an angle of 90deg. with the
scull. Do
not listen to anybody that prescribes a figure for this. The
right-angle is the
magic number for max efficiency. The scull is still floating, which
prescribes
the height of the elbows.
Now,
back to the start again. Place your thumbs
over the end of the handles. Use them to keep a slight lateral force
towards
the gate throughout the draw. All fingers over the handle, the
forefinger where the curved end of the rubber starts. Use the
fingers
as hooks – no grip, and repeat the floating stroke. The
second joint
of the fingers will contact the handle. The hand/wrist
combination is
flat.
Cup of tea
time! During the break think of this situation. Tie a piece of
string
round a small weight and place the weight on the floor. Allow the
string to
become slightly slack. Pick up the weight. Notice that the weight will
not move
until the slack has been taken up. When you take the beginning in
a
sculling boat, there are innumerable slack points in your body joints
–
fingers, wrists, elbows, shoulders, back, legs etc..
You must
contract all the muscles to be used before
the scull will move. This does not mean that you bend your arms !
Without
using your slide, repeat the above using slightly more pressure. Check
the
floating depth throughout. If you draw the handles straight towards
you,
they will still follow an arc, but the arc will be in a vertical plane,
ie the
handles will draw ‘over a hill’ and the spoons will dive
deep Assuming
all is OK, the boat is now moving. At the end of the draw, the sculls
are
removed from the water, not by twisting flat onto the water, but
by a
quick synchronised downward movement, not literally a ‘tap’
as some coaches
wrongly call it. You will have balance problems here, so leave the
stroke
for a while and practice blade extraction at the finish until you
can
return to the beginning with boat balanced and sculls off the water,
still
upright.
P A T I
E N C E !
Now repeat the floating
hook draw at full slide. You will not balance the boat yet with
upright
sculls going up the slide, so a little cheating is permissible here. It
is,
however important to remove the sculls vertically, no twisting !
Practice
‘playing the piano’ as you draw, so as not to
grip. Remember to
follow the required arc.
Now take the boat from the
water and mount it the right way up on trestles, with sculls
inserted. You
are going to learn to feather and square properly. Stand
alongside the
boat, level with the slide, and hold the opposite scull as if you were
in the
water. Push the other out of the way, or remove it. Keep the scull
approx at 90
deg to the boat, and mount the spoon upright. The challenge is to
remove
the scull from ‘the water’, flatten the spoon ( feathering
), then turn it
upright again
( squaring) , and drop it in ‘the water’ again.
- That’s the easy
bit ! You have to do it with as little wrist drop or
raise as
possible. – In my day, when cruelty was of necessity a
way of
life ( !) , coaches would sharpen a lollypop stick at both ends,
and
strap it above the wrist with an elastic band. Wrist drop or
raise
strangely became obvious !
The
early way to feather
and square is to push laterally with the thumb, regard it as a fulcrum
(
turning point ) and using friction between the four fingers and the
rubber
grip, push and pull. The scull will rotate.
Now the really expert way !
What shape is the scull button –Wake up ! – Square !
How far
do you have to rotate it to turn it through
90 deg ? 90 deg ?
Rubbish
!
The
answer is 45 deg !, which will place the button
on a corner of its square section, thereafter it will fall the
remaining 45 deg
on to the feather or square.
So back to the exercise. In slow
motion, try the above, and wait for the ‘clunk’ as it falls
flat or upright.
You will find that you have adopted a loose grip with the handle at the
base of
the fingers, and that the rotation is completed with only
the
slightest raise or lower or the wrist ( not enough to draw blood !)
Back
into the boat
! Follow the arc as pressure increases. Sculls removed by
infinite
patience, vertically. Arms away, lead with the left, equate symmetry,
drop in,
catch ( see last month ) The muscles throughout the hands, wrist,
arms
and shoulders contract at the catch, but the arms do not begin to bend!
Again,
as you draw, let the blades float, and follow the arc
!
Phew,
that was a real triple length lesson ! If you are a junior, do your
best to
understand the above, practice with your coach, as balance is
precarious
for some.
If you
have problems working it out, ask your coach
if he/she is willing to supervise you. The method may seem long,
but the
errors of the worst scullers will become obvious at some point, and
corrected,
will never recur.

Qu.
I have heard that The Ball Cup Regatta will not be held at Dorney in
2012 due
to the Olympics. Is this so ?
Ans. Emphatically
Not ! The Ball
Cup Regatta will as usual be held at Dorney in 2012. The
date is
Sunday May 13th 2012. Details
available as
usual through the link to Phil Clements on the ‘Links’
page, ‘Ball Cup
Regatta (South)’
The event should hold an extra element of excitement, knowing that Ball
competitors will be rowing the same lanes as the world’s top
crews, who compete
during the week July 28th – August 4th.
The Dorney venue will be under an advanced state of preparation in May,
and the
Ball Regatta may well this year be started at the 2000m rafts,
hopefully using
the Olympic lights and bleepers. All very exciting !

Forum
1)
Qu. In
regatta events, I am told that umpire
instructions will relate to ‘Port’ and
‘Starboard’ . At home, my coaches
still use ‘Stroke-side’ and ‘Bow-side’.
Please help me !
Ans. Pretty
typical ! I do
agree with you; I hear it wherever I go. On courses for coaches,
my use
of ‘Port’ and ‘Starboard’ is often met with
blank looks.
A few years ago, I was watching a best to be nameless regatta, when I
heard
from an umpire an amplified instruction to a straying coxless boat,
‘Move Left’
!!
Tideway crews that are not aware of the international navigation
definitions
are dicing with their lives. Tourist steamers and commercial
craft will
warn rowers in correct jargon. The skippers of such craft
are not
rowers !
So – to history ! All
the following
comment is based upon the view as seen from the captain of a
moving
commercial craft. He is assumed to be facing the direction of motion
– towards
the bow. In rowing terms, this is a cox’s view.
Before the days of stern-mounted rudders, boats were steered by an oar,
or
plank of wood, hinged over the stern side of the boat on the
captain’s right
side. This side was thus the ‘steering-board’ side –
later ‘starboard.’ (
The opposite side was the ‘larboard’ side – no real
interest to us here,
because it went out of use )
If the steering board projected over the right side of the boat, when
time came
to unload the cargo at a wharf or dock in port , the ship would moor on
the
side opposite the steering mechanism. This thus became the
‘port’ side.
Now to colour. If we are on a cross-channel ferry or similar, as
we enter
a port, we will pass red buoys on our left, or port side. Green buoys
will be
passed on our right, or starboard side.
The colours red and green thus become synonymous with port and
starboard
respectively. At night, craft carry a red light on the port
side
and green light on the starboard side. Even the largest aircraft
follow
the same convention, and yet there are still those in rowing clubs that
simply
refuse to comply with the rest of the world !
The ultimate illogicality in the use of ‘Stroke-side’
disappeared back in the
last century sixties when crews were first commonly stroked from
‘bow-side’,
ostensibly to prevent boats from ‘snaking’ due to
asymmetrical leverage
considerations.
So, juniors, correct your coaches politely – quote things like
‘Noah’,
‘Mastodons’ ‘Pink socks and caps’,
‘Bicycle clips’ !!! All
good-natured !
Some five years ago, we printed vinyl logos in red and green, worded
‘Port’ and
‘Starboard’, for sticking inside the saxboards alongside
stroke and cox’s seat,
or even on the bows of the boat. I was once asked ‘
Why do you name
your boat ‘Port’ !
If any clubs would like samples of these, email
me.
They won a safety award from the Port of London for the most
safety-minded
application for rowers on The London Tideway.
So, think and learn ‘Port and Starboard’. No,
they do not reverse
when you are facing backwards, as some supposed intelligent coach once
suggested !!
OK, so now let’s add some useful, or even life-saving,
advice for
steerspersons and coxes.
When you row on inland waters, you conventionally row with your
starboard bank
nearer than the port – or for the last time, on the right of the
channel for
coxes.
When
you meet another boat coming towards you, if they are behaving
correctly, they
will be on the opposite side ( Hence, pass ‘port to port ’
). If a faster boat
overtakes you, stay close to your starboard bank and let it pass
outside you.
Exception
to this will be on the London Tideway, which has anomalous rules for
rowers. In general, the rules relate to the direction of
tide.
Boats rowing with the tide use the centre of the channel, albeit
treating that
centre area as a water distinct from the outer lanes. So although you
use the
centre of the channel with the tide, you keep slightly to the starboard
of the centre
line. Keep well to the starboard side of centre when approached by
commercial
craft powering against the tide – they have to use the centre
channel
irrespective of tide for depth considerations.
If you wish to row against the tide, you use one of the two outside
lane
options. Which side you use is laid down by Port of London ruling,
given on
maps at all boathouses. Generally, rowing against the tide ruling gives
you an
area to the inside of a bend. When that bend runs out, you may have to
cross
the river. Be careful, boats rowing with the tide in the centre, plus
commercial craft, have right of way.
So there you have it !! Although these pages
are mostly
read by junior rowers and scullers, any coaches reading this should
firstly vow
never to say ‘stroke-side’ again, test their crews
regularly regarding
navigation, and get some of those safety stickers !
This
month we welcome as guest ‘ Girl on the River’ , Patricia
Carswell . Patricia,
a journalist, has recently become addicted to rowing, a passion
reflected on
her site www.GirlontheRiver.wordpress.com
. Her
problem is a general one that troubles many scullers
and rowers. The response deals with the specifics, but contains a
warning – do
not start guessing ! An effect may be obvious, but the cause is vague,
indistinct, and must be prised out in a cold logical sequence.
2)
Qu. “
In a double, my partner and I tend to veer
towards port. In a sweep boat, we both row on the starboard side. Could
there
be a link? ”
Ans. The
advice that I
would give Patricia is not to be tempted to jump to a conclusion that
might be
attractive but has no initial reason for validity. There
are many
reasons why a boat might veer off course, and the only way to analyse
the
problem is to test the options in a logical sequence. This might take
an hour
or so off the water to begin with, but we are possibly looking at a
fault that
might last a lifetime, and well worth the time.
Let’s begin. Let us look firstly at the equipment. Is
the boat that
is used the sole property of the scullers, or is it a pool boat that is
used
generally by club members who might be tempted to experiment with the
range of
adjustments possible ? Let us assume that Patricia puts a
padlock
on her boat and sculls when not in use and that no outside agency can
meddle.
Put the boat upside down on trestles. We can, I think, trust the
maker to
provide a craft with hull symmetry. Examine the fin. These
protrusions suffer greatly during their oft-short lives. Collisions
with upper
arms on a trailer, or resting hull down at regattas, but mainly flotsam
on the
river might well distort the fin. A loose mounting might cause the fin
to
resonate during action. Check it out. If not firmly and
symmetrically
mounted, replace.
We will not go into rigger settings here, but refer the reader to the
extended
piece on rigging in the August 2011, 1) archive. Assuming
that all
is achieved, and span, height and pin inclination have been checked
with rule,
spanner and pitch gauge, we can move on. Before we do, check that
although the span might be the recommended 159-160 cm, the gates might
not be
equal distances from their respective sax-boards. There will be a
couple of
centimetres possible variation. Check it out. If the pitch varies from
gate to
gate, individual strokes will be deep or tending to wash out. This will
vary
the drag, and therefore the leverage on one side.
The article dealt with forward and backstop adjustments. In a single, a
little
leeway is permissible, but in a double, sculls must work parallel, and
more
importantly, the ‘bite’ at the stroke beginning must be
together.
An early beginning by bow on starboard side will
move the
boat towards port an imperceptible amount. Holding in at the finish by
stroke
will also veer the boat to port. Once the boat is off line, the
area
exposed to the stream will be greater on one side than the other and
the
veering will increase. Talking of which, a river such as the Wye has
considerable random eddies and motion, and is not an item to be
forgotten in
this problem. Eliminate by sculling round two opposite bends. The
stream will
tend to push you towards one, and ‘pull’ you from the other.
It is probable that one sculler is taller than the
other. Not too practical here for novices, but worthwhile
mentioning is
that a shorter sculler can match the extra length of the taller by
reducing the
rigger span. This of course demands that the length of the scull,
certainly the
inboard length, must be adjusted to match, giving both scullers equal
ability
to match each other. This is for an advanced coach; otherwise find a
modicum
whereby parallel movement is more or less achieved. I mentioned
in a
previous article that camera pics from a bridge will help here. Have a
day on
the Gloucester canal.
So, the boat and sculls are now OK. We cannot
therefore, blame the tools !
Assuming that both scullers are novices, a double is
the
best boat to return to basics and remove the undoubted faults that
occur, which
in an indefinable way generally mess up the stroke.
So, with one sculler the stabiliser, blades flat on
the
water, handles clamped together, but with just enough feather to skim
and give
stability, the other checks out the basic movements…….
Backstops. Sculls vertical.
‘Down’. Blades emerge, a
tennis ball space under. ‘Feather’, without dropping
wrists. Repeat 50
times. ! ‘Arms away’, but initially exaggerate
the lead with the
left, so that there is no handle obstruction at the 90 degree point.
Keep
slight downward pressure on the handle so that the sculls remain off
the water.
Square well before frontstops, drop sculls in and gently catch by leg
drive.
Repeat from backstops, then as confidence gains
scull slowly
and continuously. During the draw the right passes slightly in advance
of the
left, but at backstops must be in symmetry with the left. You
will
feel if one arm is drawing harder than the other. If
the
partner can be persuaded to remove the earphones, they will notice
possible
veering here and advise!
It
is possible that one leg is driving harder
than the other, leading to skewing of the body and who knows
what…..
Check it out.
Change actions with partner and repeat.
Now, go through the lot again together. This is
where the
balance is lost, the handles let go, and the boat turns over!
Let’s hope
that you are well upstream of Monmouth town bridge !
Seriously,
stay alert and keep talking. Do not hold your breaths and make all
movements
quick but smooth. Great patience is required here. Do not be in a
hurry
to move on. You are a twosome for a season or more. A couple of
sessions
achieving this togetherness will reap rewards.
You have probably been looking for a magic cure for
your
fault. Believe me, you will by now have cured it !
There is nothing like an experienced coach or
observer, but
the above can be done by the scullers themselves. The third party
is the
check out.
Don’t
forget that the previous months’ forums (‘fora’ for
classicists ?) are there to
provide interesting and valuable coaching browsing for all. Use the
link at the
top of the month’s content.

Qu.
Your championship scullers seem to regularly win medals with so little
apparent
effort. Are they super-fit ? Are there any secrets ?
Ans. To
begin at the end. There are no secrets in these columns! Our aim
is to
help scullers reach as high a standard as possible.
Working
backwards,
possibly an indirect answer…. No, they are not super-fit,
although out of
boat work does play its part to a degree. An initial observation
of some
club training policies seems to involve an oft-paranoic propensity to
challenge
human physical structure in the gym to its yield point. Applied
to
juniors and women, this is downright dangerous. Senior males can decide
the
fate of their own bodies, coaches of juniors, which may well include
potential
mothers of the future, should be aware of legal implications.
Analogies are so
valuable…… Some twenty years ago, when building a
house, I purchased a
JCB digger. It had some 14 different movement controls, eight of
these
working in tandem. The digging arm hinged in the centre and at its
base, the
bucket also, all in a vertical plane. The whole swivelled, and could be
tilted
by jacks.
I spent hours learning the
motion piece by piece. I could have moved earth quicker with a shovel
and
wheelbarrow !
But it became easier, and two
years later I was aware that the action of the machine was an extension
of my
brain. The bucket responded to my thoughts; the hand controls had
passed
beyond conscious action.
Young football-crazy Brazilians
breathe, eat and live with a ball at their feet. It becomes a body part
which
obeys the brain instincts.
The same with all sports
involving technical tools – even the horse for jockeys and
eventers – training
involves complete subconscious integration with the tool of the trade.
You can see where I am
going. How many scullers prepare for competition when they have
not
mastered the ‘ at-oneness ’ with their craft and sculls.
They are the
equivalent of the soccer player competing with a rugby ball, or a rider
jumping
with no stirrups. Learn to live in your boat !
Every sculler must initially
treat his equipment to a lengthy cosseted makeover. These columns have
dealt
previously with extensive rigging advice. Take it ! Be
comfortable !
Perform the recommended comfort movements. I did not drive my JCB in
boxing
gloves !
Spend ten minutes easily
sculling. If not happy, come back to the stage and follow the logical
adjustment sequence. Again, and again and again !
Now we start training
! Each
committed athlete has his/her own equipment or
is allocated such. Only the coach makes adjustments. Throughout the
autumn and
early winter, all boat work is in singles. Open competition is not a
temptation
at this time.
All outings are preceded by
stretching. A developing muscle becomes fatter, and therefore
shorter.
Range of movement would decrease, and this must be avoided. The
athlete
is well-clothed. Outer layers can be discarded from the boat as the
session
develops. What do we think the cycling coach is for ?!
Off we go.
The first session is a 7 mile easy paddle, each stroke
minutely criticised in a constructive way by an accompanying
coach.
Pauses are for schooling and discussion – both ways, not rest
! We are
looking for perfect bladework: early squaring, clean extraction, sculls
off the
water at a constant height, good wrist action, thus no
‘skying’ at the
beginnings – hence sculls ‘drop in ’. Above all,
quick arms away, easing into a
floating slide. The latter is incredibly important in
addressing
the apparent ‘easy action’ comment ( see later ).
After an hour or so, and 7 miles
later, the athlete is warm, and the developing perfect action is moving
to the
permanent memory section of the brain. No discomfort; the boat is
becoming part of the body. Out we get for carbohydrate
top-up !
Time for some hard work.
Not distance flogging with rate-meter and stopwatch bouncing around. We
leave
these at home; the experienced coach knows what he is looking at and
looking
for. We have a 500 metre stretch marked out, and all our hard work is
done
here. Initially, the athletes have to learn to think for
themselves,
so…..
The athlete is challenged to
scull the 500 metres at medium effort, in as few strokes as possible,
counting
the total number of strokes taken. Back to the start. Do it
again,
with two instructions; try to take less strokes and increase the
pressure. Record the count. Do it again.
As the intervals elapse, a point
is reached where the effort is increased to such a point that the
strokes taken
to cover the 500m do not decrease, but the count actually increases
. We
now work in reverse and look for the optimum- low count at fairly high
pressure.
Now,
reader, an insertion
for you ! Every stroke sculled today has a somewhat
artificial
aspect. During the hour warm-up, after each finish, the hands are
whipped
away as fast as possible. No pause at back-stops. Such an artificially
fast
‘away’ will inevitably take the body forward with it to a
degree, but this is
where the movement ‘brake’ starts to come on. As the body
reaches its required
angle of lean, all is slow and relaxed. As the hamstrings begin to
tighten, the
slide is allowed to move, squaring begins, no further body lean and the
beginning is gently looked for.
Why
? Read the previous article on
‘Resonance’. This is a condition associated
with the position of
the body’s centre of gravity at a certain point in the forward
movement at a
certain rating. It is where all ‘pitching’ (
up/down movement, or
‘bounce’ )ceases and the boat moves with smooth almost
constant
speed. The article stated that this can be
found to a
degree by complex physics and maths, but the coach can see it and the
athlete
feels it. This is what the questioner has noticed
regarding our scullers. It can be found by experimenting
somewhere
in the region formed by quick arms/body and slow remaining slide/
beginning.
All scullers and rowers will
have noticed that once in a lifetime, the boat floats forward with no
effort.
Usually by chance and pure luck, like ‘The Lost Chord’ (
ask your music tutor
!) it is never felt again !! We look for this condition; it is
the
holy grail of boat movement.
Ignore all coaching that tells
you that the forward motion in the boat is at a constant speed. No
! We
seek to eliminate resonance pitching by the above.
Analogy again. We live in
an age of energy consideration. Take an ordinary 1950s house,
heated
traditionally. Little cavity wall insulation, no double glazing,,
no roof
lagging. Most of the heat produced by the fire or boiler
goes
literally out of the window (or walls or roof) or up the chimney. This
is your
typical sculler. Gym training to lunatic level, then jumping in
the boat
and applying the same mentality ( or lack of it ). The energy
developed
within the body is used up by immense wastage and possibly a little
correct
technique. The sculler is finished before the race reaches halfway.
Our sculler’s house has
underfloor insulation, cavity wall and roof insulation ( with
aspirating
systems – note the parallels ), a burner system that does not
throw all the
heat up the chimney but recirculates it – all in all,
the owner is a
thinker, the energy wastage is immensely low, and its level, which
might
initially have been lower than that of our lunatic friend, sees the
race out in
relative comfort.
So, our sculler is looking for
Nirvana, often finding and recognising the state more frequently, until
he/she
knows exactly the right ‘note’ to hit all the time.
Back to the 500m stretch.
Two scullers. We are going interval training, but not in the
usual boring
way. Mars Bars for the winner ! Line up level. ‘You
race each
other, but, oh yes, I forgot to say, the winner not only has to finish
first,
but has to complete the interval in less strokes than the
loser.’
AAAAAAgh !! The session only finishes when we have a winner
of 5
intervals, which may have taken 8-10 500m distances.
( Yes, I
admit, we do work them quite hard ! )
Seriously, the anti-resonant
condition rules all the time, in whatever boat work we do.
With the latter in mind, the
season advances, a few head races are won effortlessly, and early
regattas
loom. Problem here, but we treat them like head races
– yes,
a 10 stroke thrash, but then relax, use the energy slightly more
quickly by
realising that it’s all over at 2000m, and keep the brain looking
for that
hotspot in each stroke.
OK, we do use the gym, ergo,
cycles and running ( what fun running 100m intervals flat out against
another
team over a 400m athletics track. Go again when your team
completes the
circuit ! ), but not to destruction. All the time there is fun,
interest
and thinking. The coach is not the enemy – he feels their pain
and shares the
inevitable gain !
Good luck – it can happen to you
! ‘It’s not what you
do, it’s the way that
you do it’ ( as the song says
! )
Have a
Good Christmas !
Given time at this end, a cynical but humorous true story of a
coach’s life and
his experiences of the best and worst head and regatta venues
follow.
Time for a chuckle ! Ho, Ho, Ho!
2) ‘
The Years have Gathered Grayly ’ - and
Grumpily !!
As I
pass retirement age and the inclement weather
blows me from the river bank into the Aga-comfort of our cottage
kitchen, the
frustrations suffered from weather-interrupted training announce my
arrival. I
clump in, unexpected. My wife views me with the semi-disgust usually
reserved
for the furry corpse that the cat has offered in exchange for extra
helpings,
pitying, but still with latent derision. The eyes dagger
the mucky
boots, waterproofs and the sculling seat that has to be mended on the
kitchen
table. Human nature being what it is, I figure that a first foray might
quell
the expected onslaught. ‘Coffee looks a bit weak. Hot chocolate
is better after
rowing. Any digestives?’
I was
wrong.
The 1939 edition of Nickalls and Mallam’s ‘Rowing’
on
which I had frittered away part of the housekeeping the previous day
in
a Hay bookshop would have been better exchanged for Caesar’s
‘Gallic Wars’! She
lights the first fuse.‘You get more like Victor Meldrew every
day! Complain, complain! Why don’t you suggest that we knock a
hole into
the lounge so that you can bring those canoes into the house! I smiled.
Not at
the intentional and malevolent K1-1X reversal, but at the compliment !
‘Victor
Meldrew! The ultimate accolade! I wave a white flag and step lightly
into the
study, the seeds of my rowing sermon already sprouting from the mud
prints
across the carpet.
Deep
down,
as we wince at Victor’s verbal onslaughts on the box, we
grudgingly and
inwardly accept, no public admissions mind you, that the man is right.
He will
not accept second-rate service; if the lettuce wilts
or the bean tin is dented, the supermarket chain has to be nuked. If
the
dustbin is not emptied, the local council is machine gun fodder. What
do we do?
We mildly buy another black bag, walk away from the phone and feel
pathetic.
So, to
rowing. I firmly pull down the peak of my Victor cap and pull the
trigger.
Where shall we start? First principles. Anywhere in life, if we
spend money, we are retail customers. A money taker offers goods or
services;
do we get value for money?
Don’t
worry
up at Hammersmith, in my book British Rowing gives damn good value.
There might
be a touch of the traditional, to be expected in
a sport that still wears pink socks and schoolboy caps, but whereas
such capers
might throw doubt on our hormonal definition elsewhere, its all rather
cosy in
boats. One small thought though, before we leave The Priory.
Why can
the following season’s regatta calendar not be finalised
as the current season ends, say by September? Every other sport does
it; European rowing associations do it. Next year’s family
holidays need
to be booked in the autumn; we must annually attend Llandaff or
Warrington
regattas as a life priority, but we don’t know when they are
to be held! Employers are screaming for vacation slots to be claimed,
but I might just be asked to row on an as yet undefined date in a
novice crew
at Putney Town. If a Prime Minister’s eldest might just make
National Schools, even the GCSE and A-levels await that sacrosanct
Holme Pierrepont date. The date of a next General Election is thus at
risk, and all because the Rowing Calendar is not published until the
new year !
Talking
of
competition…. We pay our entry fees, fill in our on-line forms,
enclose our
cheques, and guarantee that the package arrives on time. Surely some
sort of
deal has been established? (If you failed to conform
to the above requirements, move on to the next paragraph; you deserve
not to enter the draw!) So the 10% of us still in the game
give a
moment of consideration to defining what we expect for our money.
We
arrive at our head race or regatta, park the
trailer and wonder what the snaking queue is all about. Lady readers
will
knowingly tell me that it’s for the only portaloo on the site.
But no, it’s for
that quaint custom called registration. Registration is a process
whereby the
mind is taxed to ultimate limits of ingenuity to try to convince an
iron-willed
steely eyed valkyrie that you have failed to produce a piece of plastic
for a
quite acceptable reason. Pathetic reasons range from ‘It’s
in the post’ to
‘There’s a strike in Hammersmith’. One guy even told
the truth, ‘I forgot it’.
All to no avail; out came that out-dated licence to print money,
the day
ticket book.
Lets
look at
it seriously. Why does a British Rowing card have to be produced on
arrival ?
What devious ploy does it prevent? It simply
shows that the name and number that you have forged on the entry
form match up. The international bearer has probably applied for
several, all in different names, so that he can enter both men’s
novice pairs
and heavyweight women’s open sculls. Did British Rowing check on
application
that he really was who he said he was? No, surely the only point at
which
cards need to be checked are those of a winning crew
while
still in the boat. All else is subject to simple subterfuge.
My
icing-on-the-cake-sugar-and-cream regatta is the one that has a
fast-track
registration table for those clubs that have prepaid in full at entry,
whose
crews produce instant up to date cards, with immaculate entries. One
can really
leer with glee at the confusion reigning alongside as the minutes to
boating
tick relentlessly away.
Now to
civility. I arrived at a Thames head race this season as a
stranger, parked the trailer temporarily to seek some advice, found
nobody, and returned to be regaled by an apparently
deranged being
in brogues with a clipboard who told me that my crews would be given a
false start ( it’s a head race, mind you ! ) if my wheels
did not start
turning forthwith. I asked him to quote the international
statute
under which this dire threat would be applied, took his instruction
literally,
wheel-spun a puddle of mud over his brogues,and pottered
off. A
spirit
of disillusionment had been sown that guaranteed not only a non-return
to that place for my club, but further proliferation to be spawned by
accounting the experience during bored mid-division yawns to any
interested
party in seasons to come.
Talking
of
head races and contracts, what exactly are the services
offered for our money? We bump into all sorts on river banks, none of
whom wear
their weekday weeds; it’s the public equivalent of being in a
nudist colony; we
are all equals. I discussed this very contract point
with a gentleman on a Surrey bank one wintry afternoon. He asked me
why
we came. I said that there was no logical answer to that question,
other than
the fact that all rowers and camp followers were by definition stark
staring
loopy. He smiled, recognising the affliction.
We
discussed value for money. He gave his opinion. ‘We do not
pay for the competition or the exercise,’ he stated, ‘There
has to be something
more tangible to define a contract. I submit that we pay
for the chance to win a prize. We cannot guarantee that prize, so the
chance of winning is the nearest thing to it, unless the race is
cancelled.
In the gambling world if you bet on a horse and the race
is
cancelled,
you cannot win, so by law you cannot lose. The bookmaker is not
entitled to take your money. Res ipsa loquitur’.
I was
impressed, having had fifth declension Latin female nouns beaten
into me at the age of twelve, followed by irregularly applied and
totally
uncomprehended passive verbs similarly injected a year later. I nodded
sagely.
He read my vacant mind. ‘The matter speaks for itself’.
He turned out to be a barrister.
Later I
trotted off to the race secretary. My sculler had just won a
division in which there were only two competitors. The prize was
withheld. I politely quoted my newfound friend and asked either for the
prize
or my money back. I was impolitely refused. I have not returned since.
We wait
around an awful lot at heads. It may be cold in boats waiting
at the start, products of the respiration process
uncomfortably
swelling bladders, but do competitors ever appreciate the agonies
of the
spectator? Boredom ! No programmes to read. Flasks and sandwiches
left in the car that we were instructed to disconnect from the trailer
and park
in the next county, containing umbrellas, gloves, the spare sculling
seat, all
our tools and everything from a copy of ‘The Sun’ to a
newspaper! We suffer the first division, but thereafter……!
But
it’s not
all moans! What does one head do after the first division?
It provides and prints results within ten minutes. Comparisons can be
made,
opinions disputed against results, euphoria or dejection. Before
we know it, the second division is over . Lo and behold, an up to date
printout
in a different colour is distributed free of charge. The process is
repeated.
Each boat has its time given to it as it passes the finish, and prizes
are
awarded within ten minutes of the end.
Only one
downside. This head is now oversubscribed and has to
limit its entries to ‘first come, first served’. Compare
this to a head
down the road. First division 11.00 am, results after 5.00 pm, if we
are lucky
! We’d gone home!
‘Instant
results,’ you say. ‘How?’ Ask any 12 year old.
‘Type into
your final spreadsheet column
=IF(AND(G2<>”DNS”,H2<>”DNF”),H2-G2’”NTT”),
highlight all diagonally from top right to bottom left and press
‘Enter’ !’
Damn,
the 12
year old is telepathic. ‘What about us, granddad? Tell
them about us juniors! We are the disillusioned, the unwanted. Told
that we are ‘Oarsome’ and given little chance to prove it.
It was a good idea,
but we tinies are competitive. We need races. At the age of 11, its no
good telling
us that we can race when we reach 14. Remember our favourite repost;
“ I’m
bored!” A bored young competitive rower quickly becomes a
footballer , an
angler, a follower of the now-twilight
Wilkinson cult, or respectfully, whatever is the young lady’s
equivalent.’
We do
our
homework on this subject. From every ten head entries
entered below J14, half find no competition, 2 have to race a year
group older,
the remainder are asked to row against the clock with no competition,
or worse,
told as above that no prize can be offered. ‘We have to
make a profit’,
the organisers whine. ‘It takes juniors too long
to get to the start!’ Did nobody ever consider the phrase
‘long term
investment’, or the fact that in novice fours there were 21
entries at £8
per seat; only 5 medals at £5 to be bought!
There
are
exceptions. One midlands oarsome club religiously hosts a 3 division
‘tinies’
head every autumn, and very relaxed fun it is too. No bickering, no
booze, no
foul language – but then, there are no adults!
It’s a shame that others that would do the same fall into the
mire of the
British Rowing event application process. Its all too complex to host a
regatta, so why bother. Clubs try the easy alternative of an invitation
event,
but are still clobbered; limitation on entries,
insurance (understandably)
and so on. Please, British Rowing, deal with this at HQ, not the Outer
Hebrides
regional council that only meets at sheep droving leap year Shrove
Tuesdays,
and who not only lose the
draft minutes during the fight to decide who shall not be secretary but
can only switch on the electric typewriter on alternate Sundays.
Damn me,
these expletives are echoing around the kitchen; either my marriage or
my
dinner is at stake, possibly both. That clatter was the already broken
sculling
seat ending up outside the back door. Anyways
up, the laying down of many of rowing’s frustrations does to a
degree alleviate
the house-bound days until the river becomes boatable.
January 2012 Forum
1) Qu.
I am due to take my first outing in a single, and am
distinctly
worried. Can you give me any advice ?
Ans. Most
definitely. The response is in two
parts; the first is easy. Do not go
out
in a single if you are worried. Talk to
your parents and responsible members of your club and tell them of your
apprehension. If you feel any degree of
pressure, walk away.
The second
part is detailed, and is addressed to any coach that is responsible for
boating
novices in singles.
If a
sculler / oarsperson is to progress, a single is a necessity, but
caution is also
a priority. Forget the bravado about
capsize drill, making such an event sound almost an inevitability. Preach that capsize is unlikely, and that any
immersion is the fault of the coaching, not the sculler !
Psychology
is initially the key. We all know that
survival is one of the basic animal instincts. ‘Flight
or fight’ ( or first outing in a
single ! ) induces a huge
adrenaline kick, and all else ( which includes the most logical
informed
coaching ) goes out of the window ( or over the side! ).
There must
initially be a partnership of complete trust.
‘ This coach will
not let me fall
in. He is deeply concerned with my well-being, and I trust him/her
absolutely. ’
‘ This
sculler is at the most difficult point of her/his career. I am in a
position of
complete trust. They must stay dry.’
This is my
process…. Much of the first outing
in a
single is related to the machinery !
Put the
novice in a double in the stroke seat, with the coach sitting behind at
bow.
Talk the sculler through the safety aspect. Talk about hands clamped
together
with sculls feathered on the water. Gently
rock the boat, indicating that in this
position, capsize is
impossible. Separate the hands, ‘up
–
down’ . The boat will rock in
twisting
mode, but is still stable. Returning to the ‘hands together
lock’ will give
complete stability.
Coach
stabilises the boat and sits
sculler at backstops. Forget feathering, keep sculls squared. Drop in
the
water, and ‘Up – Down’, ‘Port –
Starboard’ with the handles repeatedly. Boat
twists, but is safe. Coach eases blades off the water and lets the
sculler feel
for balance. When it is lost, GENTLY
remind the novice that letting the handles go and grabbing the side of
the boat
is not exactly the best way to progress ! Embed
this thought in the psyche.
At
this point refer back to the basic
stroke in a previous article. Hundreds of them. The novice will soon be
able to
move the boat, still with the coach balancing, fairly efficiently.
Turning
the double round is an
excellent confidence drill. Keep the
sculls squared. Demonstrate that
although drawing the scull will produce forward progress ( plus
individually will begin to steer the boat ), the boat can be sculled
backwards
by turning the scull ‘inside out‘, and pushing the
handle. ( Also a steering
effect ). Do this repeatedly with each hand singly. Then
scull backwards with both hands.
‘ Apres ‘ad
nauseam’ ’, “pull one, push one”.
The
boat will turn on the spot with hardly any alternate sideways movement. Change hands. Repeat. The
clever bit is to push one and pull the
other at the same time ! The brain will
object to this, but kindly tell it that it is learning a new skill,
just like
walking, talking, and that it is all part of its owner’s
expectation ! The boat will
now be turning in a full
circle with no bow/stern movement. (I coached an eight on a canal once
that was
only wider than the boat was long by a couple of feet. The
push-pull syncronisation turned with no
delay or damage.)
For
the future, indicate that it is
often easier to turn a boat by backing down with one hand, throwing in
the
necessary draws with the other, especially if turning after sculling
with the
stream. Drawing only will not only hit one bank, but over the horizon
or the
weir as well !
So
our sculler can now manoeuvre and
turn the double. These learned skills
can now be relegated to a deeper part of the brain when taking the step
into the
single.
Prior to
boating the novice sculler, the coach must go through a check-out
process. How deep is the water on which we
are
operating. Is there a current. Does the shallow water near the bank become
noticeably deeper as we move nearer midstream. Do
I have a throwline to hand ? Might it be handy to
have a launch
harmlessly pottering about? These items need not be broadcast to the
sculler.
If
the sculler is genuinely known to be
a strong swimmer, fearing no water situation, and it is summer, it
might be an
idea to put a capsized boat with sculls into the water, and ask the
sculler to
initially wade, possibly swim, to the bow, and return the boat to the
stage.
Then practice removing sculls, or at least one, from the inverted boat,
and righting
it, replacing the removed scull. Reminding
the sculler of the hands clamped position,
ask him/her to get
back into the boat, from one side, giving advice about centre of
gravity etc. Make it playtime ! ( Wash out mouth with disinfectant after
session, plus shower )
The above
paragraph is probably the exception, and we return to the somewhat
apprehensive, but trusting novice.
The chances
are that our beginner is a smallish junior, and that the boat is rigged
too
high. Take it out, put it on trestles,
and go through the rigging process dealt with in a previous forum item.
Put it
in the water.
Tell the
sculler that the boat is firmly locked to the stage with no movement
possible.
Coach clamps it in this position, possibly with a block under the
rigger/gate
end to keep it level. Sculler is
instructed how to embark. One foot on
the deck, hands on saxboards at base of rigger. Take weight on this leg
and
swing the other onto the stretcher plate. Sit down.
Disembark and repeat several times.
Introduce the sculls,
which will have been
placed nearby. Put the stage side scull
in its gate, handle towards the stern, making sure that it is in front
of the
pin, and its correct red/green coded side. ( See previous on
‘Navigation’)
Show
the sculler that the boat is still
firmly held, and that they can lean out on the water side, undo the
gate,
insert the scull, and drop the latch, making sure that the tightning
knurled
nut is firmly seated. Failure to check this is one of the most common
reasons
for capsize, when the scull pops out of gate.
Sit
the sculler at backstops, instruction
not to initially use the slide, holding both handles together in the
safety
position, with sculls feathered. Stress
again that in case of problems, clamp the handles together, relax and
regather
confidence. The feet are placed on top of the shoes, not in them. The reasons are not expounded to the sculler.
Tell
the sculler that you are going to
ease the boat away from the stage, keeping it level, and that you will
not let
the scull spoon go until the sculler is happy.. Handles still together. Boat is now just in excess of the landward
scull length away from the stage, and the coach tells the sculler that
he/she,
the coach, will now let go of the scull. Instruction - ‘Do
nothing,
breathe easily, sit up comfortably, keep the handles together, and
survey the
world around, including over each shoulder.’
Chat
to the sculler for a few minutes about
nothing in general. Take the spoon end,
bring the sculler in and disembark. Quiz
how they feel so far, and whether they are confident enough to go
further. Most will be highly chuffed and
confident
enough to get back in. Embark and return
to the ‘free-floating’ position.
The
boat is still sufficiently close to the
stage for the coach, if required, to grab a spoon, and the sculler is
asked to
do the hands raise and lower exercise that they met in the double, the
boat
twisting. The sculler will by now
automatically return to the safety position at the end of each exercise. All good and smiles so far !
A
bit further ! Sculler
now clamps handles together with one
hand, and the coach instructs sculler to lean sideways and put weight
on base
of the rigger. The boat is still quite
stable, albeit the weighted scull slowly submerging. Do not protract
this, but
return to the one-hand stability and repeat for the other side. Tell the sculler that the reason we do
this
is that capsize is never an instant process unless the handles are let
go, and
that a considerable amount of off-centre inbalance is required, and
that in
extreme slow motion, to roll a boat over with sculls out horizontally.
If
the sculler is confident, let them lean
out further, and bounce the rigger up and down !– the boat is
still stable as
long as the handles are clamped.
Wow, I’m nearly a sculler !!
Now for
propulsion. Let the sculler
lean
forward, and prepare to scull will one blade. He/She
will create just enough ‘lean’ on
the other blade to use it to
create stability on its side. Not too much, not to little.
Just as in the double, scull a few strokes
with one hand. The boat will, of course turn towards the bank or away
from it.
If the
latter, the coach instructs to stop and stabilise.
The sculler might feel uneasy away from the
bank. This is where the backing practise
in the double enters the arena.
The
bow might be facing obliquely away
from the bank. Coach explains that we are going to return, initially
straightening parallel to the bank. One
hand stability, drawing or pushing with the other, until the sculls are
within
coach’s reach again.
Huge congrats and praise !
Now,
before we scull with both hands and
while we are competent on the one hand stability, we are going to
practise
turning the boat around in alternate directions.
Push
the sculler away from the stage (
Note that terror has fled !) and instruct to back down with either hand
for
3/4 strokes. The boat will now be well
away from the stage. Keep talking and convince that all is still well.
Instruct
to pull for a few strokes with the opposite hand. Keep the bow off the
stage,
and back /pull alternately. The boat will have turned a complete circle.
Change
hands, and rotate in the
opposite direction. The sculler will by
now be pushing and pulling harder, feathering and squaring, the boat
twisting,
but all within a new-found confidence range. Reminder:-
we are still at backstops, and sculls are
not feathered off
the water.
Disembark to award medal !
The pupil
will not need any encouragement to get back in, and maybe the coach can
introduce self-embarking, depending on the type of stage.
If there are hand-holds or cut-outs, clamp
the rigger to the stage, and keeping the weight to the landward side,
step in. Coach
wary for outward leaning !
Away
from the stage again. If the
sculler is confident enough, the coach can ask the pupil to withdraw
the scull
a little from the swivel and push against the coach. The boat will
drift away
from the stage. Later, the whole scull can be withdrawn and pushed
against the
stage – but as and when confidence builds.
Now
the sculler moves the boat with
both hands, and the coach follows at a walk, talking all the time. Inevitably the slide will creep into play
–
keep it back !
A
scull will get tangled. Talk
about ‘twisting’ to remove and revert to
the safety position each time before continuing. At
the end of some 20-50 metres, do a turn,
as before, and return to the stage, turning again.
If
several novices are being coached at
the same stage, as confidence grows, they can compete in ‘turning
races’ – ‘1st
to complete 5 rotations in opposite directions.’
Or ‘ Race
50 metres with a turn at each end, once conventionally, once backing
down all
the way’ !
Teach
stage approach. Initially,
well off the stage, give the boat
movement, and lean gently on one part-feathered scull. The boat will
turn in
that direction. Practise with increased
speed and harder lean, the scull more severely nearer the upright. The
turn is
sharper. Make the sculler aware that
this is how a stage approach is managed.
Now
the real thing. Approach the stage
at about 45 deg, the coach tells when to drag, and the boat will either
stop 3
metres off the stage or try to ram it head on !!
Off you go and try it again !
Just like the
‘Lost Chord’ last month, one
approach will be perfection, and
the coach casually says ‘Hello, that was rather smart, you
don’t need me ! Out we get and
let’s have a cup of tea ! ( By the
way, I will still hold the rigger while
you remove the outer scull !)’
Seriously,
I do not see how it is
possible to capsize a novice sculler at any point up to now. They will
do it
themselves in the future as confidence goes sky-high, but fear should
have
disappeared, and that was the main part of the exercise.
I
cannot forget an image of a 13
year-old beginner, initially determined but somewhat fearful, having
progressed
as above, now asking for more ! I set
her off the stage, and asked her to hold the sculls with one hand.
‘So, what’s
new’, she politely said. ‘Now
stand up
with both feet on the slide deck, still holding the sculls.’ No problem ! ‘Now
stand on one leg, holding the other
sideways’ No problem !
‘ OK’, I said, ‘Do you want to go
for gold ?’ Affirmative. ‘ You are leaning down to hold the scull
handles. Bring them back to
your deck front, put one leg in front and one behind them to make a
‘shin-clamp’,
let go with your hands and wave your hands in the air !
The
spare kit went home dry !
12
months later, as a Nat Champs J-14
gold medallist, she confided that she would never forget that first
novice
session !!
The above
is , of course, dealing with the important coaching aspects. A club
will be
running safety courses,capsize and swimming drills parallel to its
boating. The carrying and racking of
singles and
doubles will be competently explained. ( No single or double should be
carried
at their extreme ends. They will
flex,
bounce and crack, not in one go, but craze over a period and lose all
rigidity
).
Good luck –
Let’s see an increase in the number of Ball Cup singles in 2012 /
13 !
The
introduction of slide work following the above is dealt with elsewhere,
as is
conventional sculling coaching. We
remember that this month we have hopefully allayed the fears of any
aspiring
singles champion.
February 2012 Forum
A
quick perusal of the rowing websites tells us that ergo machines are in
the
news. Siemens, the British Rowing
sponsor, has put out a photograph of a female athlete ( no prizes for
guessing
who ) on a Concept ergo.
This
has been flayed
regarding posture and application by Rebecca Caroe, who hosts her own
RowPerfect
site. Mailed responses have been
entertaining and varied !
It
is thus incumbent of
this site to make comment which is helpful to juniors who have probably
not had
a great deal of technical expertise and coaching applied in the ergo
field.
Ergo is a
colloquially shortened version of ergometer. Avid
students of these columns will know from
previous pages that the
source of the title came from the pre-MKS system of units known as SI (
Systeme Internationale ) .
The erg was a very small unit of energy, or
work. Its value was defined by lifting
about
a thousandth of a gramme through a distance of one centimetre – a
ridiculously
small amount. Hence, all practical
measurements involved huge powers of ten, well into millions upwards.
Anyway, the
name stuck , so let us initially examine the machine, of
which the Concept version is the most common. We
must say initially that the Concept machine in
its basic form does
not mimic the rowing stroke well, and to that end, contact Rebecca
Caroe and
RowPerfect !
The user moves up and
down a conventional slide, with feet anchored in
shoe plates not dissimilar to a boat. The
oar / scull is a single handle mounted on a
chain which passes over
a gear wheel in a housing. The gear is on a free-wheel and attached to
a wheel
which has the property of Inertia. This means that there is resistance
to starting
to revolve or further,
angular acceleration, and an ‘unwillingness’ to stop
revolving.
As the wheel revolves, air is driven out from
the housing from louvres, or spaces, whose size can be adjusted on a
common
scale of 1-10. When the
louvres are
closed, air flow is restricted, and a greater resistance to rotation is
experienced. The wheel, if left, will slow under friction and
eventually stop.
Regarding technique, we
must initially state that many users of ergos
are not rowers and use the machine for general exercise, recreation, or
at a higher
level for competition. At the
latter level, high scores at
national level can be obtained without recourse to technique associated
with
sculling or rowing - Straight up and
down the slide, no thoughts of boat run or the space limitations
imposed by
blades / sculls in the confines of a boat.
Good luck to
the latter, but we are coaching for boat work, and this has
to be a major criterion in ergo use. So, let us get down to
technique. Most clubs will have posters
from British Rowing on the walls of their gyms. These
are valuable, but if we refer back to a
previous forum article,
correct back / slide coordination is a natural sequence of familiarity
with the
feel of a resistance load. I know of
nothing better than the isometric ( no movement ) anchoring of a body
in the
sculling boat on land.
( Take the trouble to
research this – it could be the answer to the
bum-shovers’ prayer ! ) .
The handle
shape is worthy of discussion. The
original handles were simple straight
wooden cylinders, attached to the chain. Disadvantage
here is that they do not mimic the
angles of a scull /
blade handle at beginning or finish. Concept
‘evolved’ a handle that is bent
in the middle, each end angled towards the
athlete. Fine at the
beginning, but useless at the finish, where a powerful finish causes
the hands
to slip off the handle. I throw the
latter away, and return to the original wooden handle.
( An assumption here is
that we juniors cannot afford or are allowed access
to the evolution of the sculling ergo, complete with handles –
the lot ! For many years to come most
athletes will still
use the original Concept machines )
Grip ! This is a really
onomatopoeic word ( Sounds like it is !
) Try to forget it !
Draw the handle with four
fingers on top and thumb underneath. Many
athletes put their thumbs over the top
with the fingers, or place them flat along the handle.
NO ! As a test try to
do a pull-up on a bar with thumbs
under or over. The ‘unders’
have it by a mile!
Regard
the fingers as hooks.
You will never dislocate the joints in a month of Sundays. Neither will
you
cramp your forearms. You do not have to feather or square, so all is
very
simple. Let’s take a few gentle strokes…..
The
end of the stroke is as
in a correctly adjusted boat. The
handle draws to a point in the region of the lowest rib. It travels in a straight line to that point from a
start about half way up the slit from which the chain emerges. Mark this point with white tape !
Many hapless users run the handle through a
maze ranging from the ceiling to their legs, ending at chin, eye level
or groin
! ( see the Siemens pic ) Think about
the above as you gently try a few strokes.
At
the end of the draw,
imagine that you are in a sculling boat. You have to remove the sculls
from the
water, so on the ergo, handle down to just hover over the thighs. Come
forward
by aiming the handle in a straight line
again at the white tape.
Why are
you running the handle down your shins to the ankles, and thence
vertically to
the beginning position !!! ?
Straight lines rule all !
As
we are not gripping the
handle, the anomalies of the beginning and finish per the straight
handle do
not cause problems. The hand simply swivels at the base of the middle
finger to
accommodate for the straight handle problem.
Elbow
position at the finish
causes heated discussion. No argument. Physics again to the rescue ! In a sculling boat, the finish is such
that
the forearms are at ninety degrees to the handle ( think again about
opening a
door – previous ), and the forearms are in the same plane as the
line of draw.
( A plane is an imaginary surface, like a table top ). So, in the ergo,
the
former is impossible, but the latter, with elbows at handle height, is
correct. Many very experienced
athletes lower their
elbows below the efficiency plane at the finish ( Again, sorry, Siemens
)
Now
we can ‘row’ the ergo,
what can we do with it ? There will
be
an electronic display, whose complexity is often to the detriment of
the user. Basically, it can be adjusted
for distance
and time; ie how long it takes to row a given distance, or how far you
row in a
given time. It gives ratings, ie how
many strokes per minute ( ~20 - 40 ). It gives ‘splits’,
how you are doing at
intermediate points. And more !
I
split ergo use into three
categories. 1) General fitness – low level work at extended
distance and time,
eg 5-10 k metres
2) Medium to high intensity work aiming at a
distance / time relevant to competition. Eg 2000
m for lightweight women in approx 8 min.
This is where ‘interval
work’ comes
in. Divide your target distance and time
into, say eight. For the above, this will be 250m / 1 min.
Can you achieve this ? Probably.
Do it, or set a lower target.
Wait for your
pulse to reduce to about 120 and do it again… and again… Stop when discomfort becomes distress, and an observing coach instructs you.
3) Power work –
strength. This
is a
personal option to weights work. Set the
display on ‘Watts’ ( Power ) How
high a
reading can you obtain in a single stroke ? 300-350
W ? Take
a breath and
do it again and again, only stopping when the reading reduces to 80% of
your
maximum. Failure to row within this
range aborts the attempt. Start again ! You will probably do about 6-7
strokes.
Rest to 120 pulse and repeat twice more.
Different
clubs and coaches will have various and more complex versions
of the above, and I place readers in their hands. The
above will iron out many of the misuses
practised on the ergo, and will surely not be other than approved of in
the
general debate.
Remember,
‘Simple is Best !’

Qu.
What is the most important part of the sculling stroke?
Ans.
‘ Right
Angles Rule ’ OK ?
Avid
readers of the earlier forum content will be aware of the frequent
reference to
right angles. ( Ninety Degrees ? )
A brief content this month grouping
together instances where geometry and efficiency go hand in hand.
As an intro, imagine that you have to
open a very heavy ( massive ) door. Where
do you put the handle ? Easy – as
far away from the hinges as possible.
The next stage we take for granted, but
at what angle to the surface of the door gives us the easiest option
for
opening ? Obviously a straight pull or
push – Ninety degrees to the door surface.
OK – Now lets look at last month’s
forum – use of the ergo. Think
of the
legs during the stroke. Is the effort
recorded on the screen constant during the drive. No
way ! The most efficient position
with regard to the legs
is the point at
which the thighs make a right angle with the shins.
So, advice ? Make
the drive effort a maximum as this angle is
approached. Similarly be aware of the
point at which the
torso makes a right angle with the thighs. Before
or after is less efficient, so work hard at
this maximum point. Better
still try to work them in tandem..
You will feel the extra effort required to match the double right
angle, but if
you can do it, the reaction on the wheel gives you a massive boost to
your
score.
Now let’s move into a single scull and
think of the beginning of the stroke. Easy,
you say, just draw the handles towards you.
What do you notice ?
The handles rise and the sculls scrape the bottom of the river !
No, regard the handles as moving in an
arc with the swivel as fulcrum. The
wrists and fingers have to adapt to as close to this ideal as possible.
Why ? So that in an ideal state, vitually
impossible, the forearms make an angle of ninety degrees with the
handle. As before, impossible, but get as
near to it
as possible – certainly mentally. The
sculls will now move at their correct depth.
The most efficient point in the sculling
stroke? Answer as above ! When the
arms
are at 90 degrees to the handle. Plus of
course all that we said above regarding the leg joint angles. Oh, yes, the scull spoon is also acting
at
90 degrees to the motion of the boat – another most efficient
condition.
So, if we recognise all the above, and
not only apply max effort through these right angles, but take care not
to
slacken the effort at these points, you will really notice the boat
punch !
End of sculling stroke ? If
we recognise the above middle of stroke
condition and try to maintain the 90 degrees towards the finish, what
do we
have to do ? The elbows and upper arms
leave the side. How far, we are asked
frequently ? No distances mentioned.
We
end the stroke with the forearms at right angles to the
handle
!
Clever ones among you readers will
notice an obvious unmentioned flaw. Viewed from above ( plan ) the 90
degrees
can be maintained, but the forearms and elbows might be raised or
lowered relative
to the direction of draw. Lost you ??
Think back to the heavy door. We
obviously push or pull at right angles, but not in an upward or
downward
direction as well.
Back in the sculling boat, think of the
direction of draw as a polished table top. The arms and elbows slide
along the
surface. This is called movement in a
constant plane.
So, briefly,
this month , there you have
it ! Think right angles ! Can you spell Pythagoras !
Of course, now try someone with Isosceles !

Qu.
How can we prepare for The Dorney Event ?
Ans. Good question, as for many juniors, this is
the big
event of your year.
Most of you will not
have experienced a six-lane regatta before, and the vista as you arrive
can be
awesome. For many coaches, this can
also be a big deal, and scullers can help a lot before you leave home. Captains and strokes should be on
top of
your individual events. Know your times,
know your opposition. Know your lanes, events and colour codes. Be in charge of boat rigging.
Coaches cannot be
expected to do all these things.
There is nothing worse
for a coach than to observe crews just lolling around doing nothing !
Before you leave home, a
complete session should be devoted to turning a boat and backing it
down onto
an imaginary pontoon. Be aware that
at
Dorney, a strong side wind from starboard ( archaic bow-side ! )
usually
applies. Allow for this. You should all be able to scull a boat
backwards, at least in a straight line.
The above is the most
important of the day. Crews are now
regularly left behind if they cannot attach to pontoons and hold the
boat
straight.
Be aware of the ‘ Give
LH scull to the person in front ‘ technique to hold the boat
level in a side
wind. If you are not aware of this, ask
your coach to demonstrate.
The nonsense of holding
up a hand if so called ‘not-ready’ applies.
You will be started in the opinion of the aligner
and starter. Be ready to scull the
moment you are on the
pontoon.
Good luck !
Get your sculls down to
the stages before the boat is carried, and get them away after the race. Many are regularly broken if left
around,
and marshals cannot hold up boating while you wander away to get
equipment !
Assuming that you get
through the first round, replan your timetable, and repeat the above.
WEATHER. May can
be a heat wave or freezing. If the
latter, you will not be allowed to boat if inadequately clothed. If the former, sun-cream and head cover
apply ! Thunder storms or
rough water
often apply. Coaches should
adjust
rigger height accordingly. Many very
adequate crews have been unable to scull because blades will not clear
the
waves !
Watch out for damage
possibilities. Dozens of
trailers and
towing vehicles regularly knock the ends off boats and crush sculls
– once a
sculler as well ! Don’t blame
others,
foresee the possibilities.
Apart from that, I look
forward to seeing you all as I take a
relaxed wander during the day !!

Forum
Qu. I want to learn to help my coach
rig
boats. What tools should I ask for as a
birthday present ?
Ans. What a valuable creature you are ! Read on.
As the 2012 Ball Cups approach, there is going to be a
plethora of
rigging; boats to be derigged and loaded at home, rerigged for
competition, and
the whole process reversed after competition.
It is a useful exercise in
many aspects of the sport to imagine that the coach is absent for a
session. Does everything grind to a
halt, or do enterprising crew members step in and carry on ? Are you one of these ?
Let’s start with the
competition boat on its home rack. Carefully
lift onto trestles so that the weight is
evenly
distributed. If the boat is sectional,
imagine that when split, each half will exactly balance on its
supporting
trestle. If non-sectional, the principle
still applies.
First tool needed is the universal 10 mm
spanner. The size refers
to the nut that it turns. Rigger-jiggers
are expensive, besides which you need both a ring and an open end on
each
spanner.
Overriding advice in this article is to
find your local engineering
supplies retailer, the place where you buy screws, nuts, bolts, drills
and all
sorts of mechanical and electrically driven tools.
Yellow Pages is the answer. Pay a visit,
browse and ask questions.
You will buy three spanners
as above for a price compared to a single from a rowing supplier. Often there will be a counter bin with a
variety of spanners for mere pence. Two years ago I bought 50 Ten mm
spanners
for 30p each !
Why both ring and open end
? If your sculling boat has a forestay
or awkward-angled stays, the ring will not seat over the nut, and the
open end
is needed.
When removing the rigger
nuts, either find a friend to support the rigger, or at least leave the
centre
top nut until last. You should find that
there will be a washer between nut and rigger. If not put one on as you
rerig. On this point, buy
washers and nuts while at the suppliers. Cheapest buy is a box of 500 of each. Mere
pence or
less each ! Why not measure
your rigger bolts and buy a couple of dozen of these also as spares.
It is unforgivable that
many clubs scrape and
scrounge to find a single nut. I poured
a box of 1000 onto a table at a TSS coaching course – eyes popped
out of heads
!
All the above should be asked for in
stainless steel. Anything less will rust,
which in turn will rot
the wooden frames inside the boat shoulder gel coats.
Sizes of bolts to fit 10mm
nuts are 3mm diameter, obviously metric thread.
So, all riggers off ! How many nuts and washers lost ?
Several ! Multiply this
by four, and you will know why
futuristic archaeologists
will wonder why small bits of steel are regularly found on rural river
banks ! Hence the need to buy a box full !
Next spanner size, also
double ended open and ring , is 13 mm. This
will not only fit some section bolts, but more
common in use,
rigger gate mounting and top bolts. Again,
buy several (
It might be
useful here to buy a couple of 12 mm spanners in case you meet a few
‘foreign’ nuts. Splash paint
on to tell the difference –very
close in size.
On to sculls. Most clubs have
afforded ‘posh’ sculls these days, adjustable not only at
the button, but in
overall length. You
can buy either a set of ‘posi-drive’ screw-drivers of
various
sizes, or 2 or 3 individuals. Not a
bad idea to take in a scull button, and choose a head to fit exactly. Some bolt heads vary, although all in
appearance are old ‘Phillips-type’ .
So, all easy so far. You can
derig and rerig a boat, adjust sculls, and play with gates. What next ?
I would go for lashings, the
things with which you fix boats onto trailers, or bundle sculls and
riggers in
the bottom of a trailer. Do not buy
straps with tightning buckles, the small version of lorry load fixings
– they
can be tightened to immense pressure, and will split gel-coats on
boats, even
if not visible damage.
Go to a professional tent
and marquee supplier (
again, Yellow Pages ), and buy a reel of elastic cord.
This can be cut into 1-2 metre lengths and
used quite safely to lash boats to trailers.
You will always meet a giant
rusted nut somewhere. Add to your list a
medium sized adjustable spanner. The
most expensive piece to date, but a
real status symbol when an international eight needs to remove a rusted
gate
nut. Better still in the status stakes
is to tell them to slip the ring of a second spanner over the open end
of a
first, thus doubling the effective length of the spanner.
Nothing will resist that torque !
On the subject, how tight
should rigger nuts be ? Simple,
screw
up loosely then further until you can not tighten further with a
forefinger
pressing on the end of the spanner. Any
more gouges the rigger and indents the boat.
That should do for now. You
will be boating for Dorney in two weeks. Already, with your tool box,
you will
be the most popular person on the regatta field.
Bask in the glory !
